As illustrated in thedrawing, this invention is shown as embodied in adevice adapted to be connected with conduits supplying respectively aliquid fuel and an atomizing avent such as compressed air or steam.heans are provided for the mixing of the two elements so that aneiicient atomization will occur, and such that will result. y Y

A pipe 1 connected to a lsource of fuel supply, not shown, and a pipe 2connected to a source of air or steam supply, are secured to a fitting 3by threaded connections. A cylindrical opening 4 and a cylindricalopening 5 in the fitting 3 are continua-tions respectively of the pipesor conduits land 2. The fitting 3 has a flat perpendicular face adaptedto match the face of a fitting 6. `A cylindrical opening 7 through thefitting 6 registers lwith the opening 4 and an opening 8 of novel formregisters with the opening 5. The opening 8 is substantially wider thanits depth and has the form best shown in Fig. 5.

VThe fitting 6 has a perpendicular recess 10 registers with the opening7 and an opening 11 registers with the opening 8. Grooves 12 form acommunication between the recess 10 and the opening 11 whereby the fueland the atomi'zing agent are co-mingled a long narrow hot flame Yfducedathrough.the. conduits 11 `and 2, respectively, and into thefitting 91 wherethey are mixed,`tl ie 'mixture passingli'nto thetube`f13 where its movement causes `the.;rotationo'f the face i adaptedto match the face of a fitting 9.
